Advanced Surface Heat Exchanger Via High Strength Graphite Foam

Currently employed surface heat exchanger utilizes Titanium metal. The low thermal conductivity of titanium combines with its high density results in significantly design penalties. Applications of graphite foam to the heat exchangers offers potentialsignificant performance and weight benefits. However, the key strength, thermal conductivity and integration issues need to be resolved. Hamilton Standard will work with MER to design the surface heat exchanger with the graphite foam. A nanotubesreinforced graphite foam will be explored as means to achieve improved thermal and mechanical properties. Thermal fin efficiency will be evaluated and compared with the state-of-the-art design. This technology will be inserted into surface heatexchangers for both defense and civilian applications.
